HYDROCARBON INCANDESCENT LAMP.

SPECIFICATION forming part of Letters Patent No. 637,952, dated November 28, 1899.

Application filed October 28, 1898. Serial No. 694,766. (No model.)

To ctZZ whom it may concern.-

Be it known that I, DAVID S. WILLIAMS, a citizen of the United States of America, and a resident of 903 Walnut street, in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon Incandescent Lamps, of which the following is a specification.

My invention relates to new and useful improvements in hydrocarbon-lamps especially adapted to the use of high test hydrocarbon oils, the principal features of my invention being the construction and arrangement of the vaporizing-tube whereby the greatest possible amount of heat is brought in contact with the tube, so as to thoroughly vaporize and superheat the vapor before it enters the burner, and the construction of the regulating-valves and means for regulating the flow of vapor from the vaporizing-tube, thereby dispensing with joints, glands, or stuffingboxes and preventing the escape of vapor, which has been found to be extremely objectionable in other lamps on account of the disagreeable odor emitted from burners wherein glands or stuffing-boxes are used.

The invention also consists in various other indispensable details of construction, which will be more fully set out hereinafter.

Referring to the accompanying drawings, Figure 1 illustrates a plan view of a high-test hydrocarbon-oil lamp constructed in accordance with my invention. Fig. 2illustratesa side elevation of the same. Fig. 3 illustrates an enlarged vertical section of the lamp with the upper part of the vaporizing-tube broken away. Fig. 4 illustrates a vertical section of a portion of the expansion-tube, showing the needle-valve fixed and inserted from the outside, the joint being made by a fireprooLfiber washer. Fig. 5 illustrates a sectional plan View on the line 5 5 of Fig. 3. Fig. 6 illustrates a sectional plan view on the line 6 6 of Fig. 3. Fig. 7 is a plan view of the coupling, which is provided with a washer of non-conducting material for the purpose of preventing an escape of heat from the lamp, which would otherwise occur through the medium of the metallic connections. Fig. 8 is a side elevation of a double type of burner provided with a hood for the purpose of concentrating the heat upon the top of the vaporizing-tube. Fig. 9 is a front elevation of the type of burner illustrated in Fig. 8. Fig. 10 is a sectional plan View on the line 10 10 of Fig. 9. Fig. 11 is a plan view of the hood, which is mounted upon the top of the vaporizing-tube. Fig. 12 is a vertical section of the hood, showing the manner in which the same is secured to the vaporizing-tube. Fig. 13 is a section on the line 13 13 of Fig. 11; and Fig. 14 is a vertical section similar to Fig. 12 of a modified form of hood and vaporizing-tube, the latter being in two parts, each of which is adapted to be threaded to an opening in the hood.

Referring to the reference-letters of the drawings, A represents the body of the burner, provided at the top with a burner-head A and at the bottom with an expansion-tube A Mounted directly above the burner-head is a vaporizing-tube B, made in the form ofa loop, the members of which are detachably secured to the opposite sides of the burner-head A and are held in position by set-screws b and and b. The arm A of the expansion-tube A is provided with a threaded valve-stem D, which latter is provided with a detachable needle D, held in position by a clamp D which admits of the needles being removed and replaced when bent or otherwise injured by careless usage. Below the expansion-tube and between the same and the supportingbracket F, I find it desirable to place a coupling G, which is formed of twoparts g and g, fastened to a section g which is a poor conductor of heat, and by this means the heat generated by the burners is prevented from being carried off by the bracket F.

For the purpose of heating the vaporizingtube prior to starting the flame in the burner I use a small quantity of alcohol, which is placed in the cup H, the same being formed upon or united to the burner a short distance below the burner-head. The cup H is pro vided with arms h, which extend upwardly and terminate in prongs h, which form supports for the globe or chimney I, which may expansion-tube, while the burner-head A is separated from and arranged to move upon the lower portion A of the burner by means of a nut A by the adjustment of which the vaporizing-tube B, which is carried by the burner-head, is raised or lowered and the discharge end of said vaporizing-tube is brought into contact with the needle-valve to open and close the orifice in the nozzle A Where two or more burner-heads are employed, as shown in Figs. 9 and 10 of the drawings, 1 find it desirable to use a hood J over the top of the vaporizing-tube for the purpose of concentrating the heat from the burners. Arranged near the center thereof are openingsj, through which the products of combustion escape. The hood J is secured to the vaporizing-tube B by a clamp J; but, if desired, a curved tube J may be formed in said hood, as shown in Fig. 14, in which case the two ends of the vaporizing-tube will be threaded to the openings.

I have shown in dotted lines in Fig. 9 a modified form of device for adjusting and regulatin g the flow of vapor from the vaporizing-tube. Formed on the lower part F 5 of the burner is a projection f threaded to receive a stem f which has a reduced end f adapted to a projectionf, which latter is secured to or formed upon the upper or movable portion of the burner carrying the vaporizing-tube.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1S
